+
+ Fixed cmd_parse() so that it always skips past a full command
+ name. A few special commands for which this would be bad get

+ environment variables if other methods are not available.
+
+ glob.c: Removed a lot of global variables from glob.c and encapsulated
+ them in set.q
+
+ random.c: Tidied up the way the random seed is set.
+
+ str.c: Added a ds_vprintf function.
+
+ error.c: Extended dump_message so that messages are always broken at

+
+Sun Feb 15 23:06:08 2004 Ben Pfaff <blp@gnu.org>

+ * Updated every function that implements struct case_stream's
+ `read' function to take a write_case_func and a write_case_data.
+ Also updated every caller of write_case() to instead call them
+ through these arguments. In some cases this meant that the extra

+ * data-list.c: (struct repeating_data_trns) Add members
+ `write_case', `wc_data' as kluge.

+
+ * alloc.h: Move definitions for local_alloc(), local_free() here
+ from ../pref.h.orig and simplify.

+
+Thu Jan 1 23:09:07 2004 Ben Pfaff <blp@gnu.org>
+
+ Start working on a new output driver system, one that doesn't suck
+ so much, by adding a "device-independent" output driver. The idea
+ is to write out only a single output stream, then use separate
+ processes to translate them into whatever formats we want. This
+ is similar to how "groff" works with its various output drivers
+ (grops, grotty, grodvi, ...).
+
+ * Makefile.am: (pspp_SOURCES) Add devind.c, devind.h.
+
